본 발명은 진동 감쇠기에 관한 것으로, 더욱 상세하게는 가로등, 신호등과 같이 수직방향으로 설치된 기둥에서 발생하는 진동을 효과적으로 감쇠할 수 있는 진동 감쇠기에 관한 것이다.The present invention relates to a vibration damper, and more particularly, to a vibration damper capable of effectively attenuating vibration generated in a vertical column such as a street light, a traffic light.

일반적으로 차량이 주행하는 도로에는 가로등, 신호등, 무인카메라 설치대 등이 설치되어 있고, 이와 같이 수직방향으로 높게 설치되는 기둥은, 지진 또는 강풍등의 자연현상에 의해서 쉽게 흔들림이 발생되고, 또한 차량의 주행에 의해서도 진동이 자주 발생한다. 따라서 이러한 흔들림이나 진동에 의해서 기둥에 설치되는 전등, 카메라와 같은 전기장치가 기둥으로부터 떨어져 파손되거나, 심하게는 기둥이 휘어지거나 쓰러지는 피해가 많았다. 특히 빈번하게 발생하는 작은 진동에 의해서는 전기장치의 고장을 유발하거나 수명을 단축시켜 지속적인 유지관리를 필요로 하고 있다.In general, streetlights, traffic lights, unmanned camera mounts, etc. are installed on roads on which vehicles travel, and pillars installed vertically in this way are easily shaken by natural phenomena such as earthquakes or strong winds. Vibration often occurs due to running. Therefore, the electric devices such as lights and cameras installed on the poles are damaged or severely bent or collapsed by the shaking or vibration. In particular, small vibrations that occur frequently cause breakdowns or shorten the life of electrical devices, requiring continuous maintenance.

이와 같은 진동을 감쇠시키기 위한 진동 감쇠기로서 다양한 형태가 개발되고 있지만, 대부분의 진동 감쇠기는 수직 또는 수평방향의 어느 1방향으로 발생하는 진동을 감쇠하도록 되어 있거나, 일부 수직 및 수평의 2방향으로 발생하는 진동을 감쇠하도록 된 것도 있으나, 수직 또는 수평방향이 아닌 예를 들면 임의의 경사방향으로 진동이 발생하는 경우, 효과적으로 감쇠시킬 수 없으며, 모든 방향의 진동을 감쇠하기 위해서는 다수개의 진동 감쇠기를 설치해야 하므로, 설치공간 확보에도 어려움이 있을 뿐만아니라, 경제적인 부담도 증가되는 문제가 있다.Various types of vibration attenuators have been developed to attenuate such vibrations, but most vibration attenuators are designed to attenuate vibrations occurring in any one direction in the vertical or horizontal direction, or in some vertical and horizontal two directions. In some cases, the vibration is damped, but if vibration occurs in a direction other than the vertical or horizontal direction, for example, it cannot be attenuated effectively, and in order to damp the vibration in all directions, a plurality of vibration dampers must be installed. In addition, there is a difficulty in securing an installation space, as well as an economic burden.

본 발명은, 상기와 같은 종래의 문제점을 해결하기 위한 것으로, 하나의 진동 감쇠기로 수직, 수평방향은 물론, 임의의 경사방향을 포함하는 3차원방향의 진동에 대하여 효과적으로 감쇠시킬 수 있도록 함으로써, 기둥의 휘어짐이나 쓰러짐 을 방지하고, 기둥에 설치되는 전등, 카메라와 같은 전기장치의 고장 또는 수명단축을 방지할 수 있으며, 진동 감쇠기의 설치수를 감소시키는 것에 의해 경제적 부담이 적고, 많은 설치공간을 필요로 하지 않는 진동 감쇠기를 제공하는데 있다.The present invention is to solve the conventional problems as described above, by using a single vibration damper to effectively attenuate the vibration in the three-dimensional direction including the vertical, horizontal, as well as any inclined direction, Prevents warping or falling down, and prevents failure or shortening of lifespan of electric devices such as lamps and cameras installed on pillars, and reduces the number of installations of vibration dampers.

상기 탄성코일스프링(20)은, 케이스(10)의 상,하측에 구비된 고정지지부(12)에 양단이 끼워져 고정되며, 재질은 높은 탄성과 내구성을 가지는 형상기억합금인 것이 바람직하다.Both ends of the elastic coil spring 20 are fixed to the fixed support part 12 provided on the upper and lower sides of the case 10, and the material is preferably a shape memory alloy having high elasticity and durability.

또한 상기 탄성코일스프링(20)의 중간위치에는 금속 또는 비중이 높은 소재로 제작된 무게추(30)가 고정되는 것으로, 도 2에 도시된 바와 같이 무게추(30)는 원형의 바깥둘레면을 가지며, 이 바깥둘레면에 탄성코일스프링(20)의 코일나선부(21)에 대응하는 나선홈(31)을 형성하고 있다. 따라서 무게추(30)의 나선홈(31)에 탄성코일스프링(20)의 코일나선부(21)를 삽입하여 결합한 후, 용접등의 고정수단으로 고정하는 것에 의해 무게추(30)가 탄성코일스프링(20)에 고정된다.In addition, the weight of the weight 30 made of a metal or a high specific gravity is fixed to the intermediate position of the elastic coil spring 20, as shown in Figure 2 the weight 30 is a circular outer circumferential surface And a spiral groove 31 corresponding to the coil spiral portion 21 of the elastic coil spring 20 on the outer circumferential surface thereof. Therefore, after inserting and coupling the coiled spiral portion 21 of the elastic coil spring 20 to the spiral groove 31 of the weight 30, the weight 30 by the fixing means such as welding, the weight 30 is the elastic coil It is fixed to the spring 20.

도 3은 상기 탄성코일스프링(20)과 무게추(30)의 다른 실시예에 따른 고정구조를 나타낸 것으로, 무게추(30A)의 중앙부에 원형의 관통구멍을 형성하고, 이 관통구멍의 안둘레면에 탄성코일스프링(20)의 코일나선부(21)와 대응하는 나선홈(31A)을 형성한 것이다. 따라서 관통구멍의 나선홈(31A)에 탄성코일스프링(20)을 삽입하여 결합한 후, 용접등의 고정수단으로 고정한 구조이다. 3 shows a fixing structure according to another embodiment of the elastic coil spring 20 and the weight 30, and forms a circular through hole in the center of the weight 30A, and the inner circumference of the through hole. A spiral groove 31A corresponding to the coil spiral portion 21 of the elastic coil spring 20 is formed on the surface. Therefore, the elastic coil spring 20 is inserted into and coupled to the spiral groove 31A of the through hole, and then fixed by fixing means such as welding.

또한, 상기 케이스(10) 내에는 무게추(30)가 잠겨질 정도의 양으로 액상의 유동체(40)가 넣어지고, 이 유동체(40)는 점도가 높은 물질이면 좋고, 바람직하게는 젤(Gel)형상물질을 사용하는 것이 좋다. In addition, the liquid 10 is placed in the case 10 in an amount such that the weight 30 is locked, and the fluid 40 may be a substance having a high viscosity, and preferably a gel (Gel). It is recommended to use a shape material.

이러한 구성의 진동 감쇠기(1)에 의하면, 설치대상물의 임의 장소에 케이 스(10)의 고정부(11)를 볼트등의 고정수단으로 고정함으로써 용이하게 설치하여 사용할 수 있다. 도 4는 본 발명에 따른 진동 감쇠기(1)의 사용상태로서, 가로등(a)에 설치한 예를 나타낸 것이다. 도시된 바와 같이 수직, 수평 및 임의의 경사방향으로 진동하는 가로등(a)의 전등(b)과 근접된 부분에 본 발명의 진동 감쇠기(1)를 설치하게 되면, 도 1에서와 같이 무게추(30)가 탄성코일스프링(20)의 중간부분에 고정되어 탄성이 높은 형상기억합금으로 제작된 탄성코일스프링(20)의 탄력적인 신장 및 압축작용에 의하여 유동가능하게 된 것이므로 가로등(a)의 전등(b)부분의 진동에 따라 상대적으로 수직, 수평 및 임의의 경사방향으로 유동하여 진동을 효과적으로 감쇠하게 된다.According to the vibration damper 1 of such a structure, it can be easily installed and used by fixing the fixing | fixed part 11 of the case 10 by fixing means, such as a bolt, in arbitrary places of a mounting object. 4 shows an example in which the vibration damper 1 according to the present invention is used and installed in the street lamp a.
